Hi, i've build a gantry piggy back toolchanger for my router, driven by a stepper (with gear reduction) and a geneva wheel, and am looking for some quick pointers.

At this point I've got it to rotate, creating an extra axis in HAL / INI, nothing else.

I was planning to use the stepper 'velocity mode' to drive the stepper.
I envision I need to place two proximity sensors:

1. Prox sensor for homing pin
2. Prox sensor to detect an index step, for counting logic of the pockets
   
   How does the base Probe Basic configuration handle pocket homing (locating pocket nr 1), counting pockets and the drive signals to the motor?
   
   Some clips of the geneva mechanism:
   
   
   
   
   
   
   
    
   

Small update:
After updating almost all values get stored and recalled correctly.

One exception seems to be the Spindle_zero.
If manually entered, it doesn't get stored and recalled.
If measured via subroutine, it does get stored an recalled on restart of PB.

(Subroutine folder is up to date)

Hi Endian,

Here is a example for you. I assume you can clone the repository, do the install script.
Then you can try it out.

Hi,
I tried with stlink and j-link with errors.I also tried reversing swdio and swclk, because I saw images of pins connected differently.

Hey Scott,
Sorry to bug you again, but just wanted to let you know I finally managed to flash the firmware and ping 10.10.10.10! Next up is diving into the LinuxCNC side of things.

I’m planning to document everything I did to get it all working and might make a YouTube video showing the steps once my exams are out of the way next week. Also, I was thinking it’d be cool to contribute to the project documentation if there’s any way I can help out.


Thanks again for all your help – really appreciate it!

Hi,
how did you solve the flash problems?
could you please insert the strings you inserted? Photos of the connection pins? Did you power the NVEM V5 at 12V or 24V? Did you press the button?

Hi Rod,

The planner is indeed in it's own folder under src/emc/planner link
It uses the original Makefile to build the planner.

If you use 2 different build systems we experienced a kind off linking errors. Resulting that
the motmod.so and liblinuxcnchal.so had to be recompiled by cmake. But the excact reason why
this is, is unknown for me.






 

the ISO on the downloads page includes 2.9.4. Trixie/SID is a work in progress. Its not trivial to comply with the Debian build environment and a whole host of  QA requirements imposed by SID. The devs do try...

vi is very old-school. Nano is somewhat easier. I use it with SSH to edit files on another pc. The Linuxcnc includes geany  which is a GUI based text editor

I can't see why the new planner can't be put in its own folder under /src/emc together with its build system. Surely linuxcnc's make system can call another build environment. In fact some of the lcnc code is written in c++   

Have a look at the header files in src/emc/rs274ngc. Classs don't exist in C  

hakan is on the right track
There are a couple of xml files here with configs for Rtelligent and Deiwu I.O modules created exactly how endian menrions

 If you get a USB wifi dongle with an external antenna you can get a SMA extension cable with a bulkhead connector on the end. Drill hole through enclosure, insert fitting and attach with supplied nut, and attach the antenna from the dongle. I have done this a few times now.

small update moving forward with this.

Found another problem that seems to have fixed it. The machine is manufactured in the east, the input switches/buttons go through a wide metal clamp that I assumed was frame grounding the shielding of the wire, it was not. When I earth grounded the shield with the setp suggestion the random EStop trip seems to have stopped. It will take more tests to be sure.

Input common is Negative on the 24v PS. Limit switches are inductive and signal 24v when tripped, EStop will be 24V normal, 0V when triggered.

Yes, limits triggering will also cause a fault and change to machine-off state.
Maybe a wiring issue with the input common, or just limits/estop wired
near power signals.
